HYY DROGENATED EDIBLE FAT PRODUCT.

k i To all whom/it concern Be it knownthat' I, OARLEro1-i ELLIS, a citizen of the United-States, and a resident of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hydrogenated Edible Fat Products, of' which the following is a spec fication,

i This invention relates to a' composition- Containing edible hydrogenated. oils or fats and relates in particular to oily or fatty products. preferably of a composite nature containing v edible hydrogenated oil material derived by the hydrogenation of unsaturated oily material in a certain manner to aflord oils or fats either of a butter-like or ofa lard-like consistency or. of other desired consistency which areessentially or substantially free fromdeleterious or toxic bodies such as are sometimes present in the normal oils, and which have other desirable qualities as willbe hereinafterset forth,

I Most oils of a vegetable nature and some. animal oils contain from tracesup to considerable quantities of highly unsaturated bodies," including those-of the linoleic andlinolenic group. These and other similar bodies are very sensitive to oxidation and lend instability to such edible oil products of this character by their. tendency to change chemically and thusalter the flavorof the material. Some also contain nitrogenous or' 'otherbodles of adeleterious or toxic charto provide a composition essentiallyor substantially ffee from'these or other objectionable bodies. This may be accomplished? by very careful hydrogenation up to the degree of consistency required in the edible product,

but such hydrogenation is 'diflicult to carry out commercially on a large scale'with the assurance that the product will-run uniform in quality. Therefore, I prefer to carry out;

the treatment by saturating these bodies with hydrogen ,or other harmless additive element or radical to an excessive degree as regards, final consistency, so as to cause these bodies to lose their identity and become sub st-antially free of odor of origin and tend- L ency to rancidify or otherwise be decomposed.

AS stated in Serial No. 7 14,393, filed August 10, 1912, by hydrogenating soya bean,

cotton seed or corn oil or similar oils to materially reduce the idoin number, the-more sensltlve double bonds are saturated with hydrogen and thereby eliminated and oxi-v dation tendency is reduced-to a minimum. Apparently the complete elimination of all the double bonds characteristic ofthe linov l Specification of Letters Patent. V Patented Apr. 15, 13 13; Application filed August 15,1912. Serial No. 715,209 v r 'leic type is more diflicult'than the removal of the double bonds characteristic of the linolenlc type, so that control over this seeming selective action during hydrogenation when saturated up toa given degree of consistency from a given 011, is difiicult, if not impossible under ordinary conditions of hydrogenated so that a more consistent fat is acquired than is actually desired for an hydrogenating' If, however, theoil-is overedible product, the unstable bodies thus may. i

be completely transformed, that is to say they are chemically converted into different chemical compounds. By this over or super hydrogenation the linoleic as, well as the linolenic and isolinolenic ,bodies and the like are substantially completely transformed and other desirable deep seated reactionsoccur which afford a product possessing useful characteristics. In order to secure the degree of consistency desired I may cool the hot hydrogenated fat gradually to I about30 C. when the temperaturemay be maintainedbetween 25 C. to 35 C. ,orso for several hours to induce crystallization or balling of the high melting point compound. The mass is then pressedto the desired degree, the pressing being conducted in the manner Well known'in the art. The press cake contains the excess .of stearins and other high melting bodies produced by hydrogenation. changed oleins, some hydrogenatedbodies, unsaponifi'able oils, etc.

is then preferably bleached using for this purpose fullers earth, ozone, oxygen and the like. Fish oil preferably should be treated with ozone followed. by filtration in a heated. condition through fullers earth. The bleached oil is then combined with such proportion of the stearin as gives either the butteryo-r the lard like mass desired. Usu. lly

one to three parts of the so-called stearin" The expressed materlal contains un- The extracted oil is added, to about parts of the oil. Th'is mixture is preferably chilled and whipped or otherwise agitated in the presence of air or other gas, as nitrogen or pure hydrogen,

to give what may be termed a vesiculated -sure. Such a superhydrogenated pressed product which may be made either of butterlike or of lard-like consistency isobtained from a number of common animal and vegetable oils or mixtures of these possessing a number of desirable properties. Such products when properly prepared without resorting to ordinary forced hydrogenation at excessively high temperatures are stable in storage and are not liable to coagulate on standing with the formation of objectionable masses of granulous stearin-like bodies.

The product is free from objectionable odor and does not acquire any resinous stale taste upon standing for an indefinite period, nor does it resume its original odor on standing. Fish oil or whale oil may be hydrogenated slightly in excess and then pressed to soft tallow or lard-like consistency and bleached. The fat product will then be found free from fishy odor having a pleasant odor recalling fresh tallow. scarcely any of the original flavor remains and the very slight tang which is usually apparent is not of a disagreeable nature.

Another feature of the present product is that apparently it does not on long standing act upon tin or tin-containers so that the oil does not become more or less charged with tincompound. The hydrogenated product made under some circumstances bears a moderate addition of other ,oils

which have not been hydrogenated, .or have not been subjected to the action of hydrogen; the hydrogenated product embedding and protecting those other less stable oils from the normally spontaneous reaction or changes which they are well known to frequently experience.

The product may be made capable of standing the relatively high temperatures such as .are incident toi'culinary operations without the formation of acrolien fumes and other, objectionable bodies. v

Another very desirable [feature of the product in its preferred form is what may.

be termed the melting point lag, involving a blowing with superheated steam at of a titer expressed as the solidifying seemingly peculiar lack of immediate response to temperature fluctuations which is often very pronounced and which enables the production of soft edible products not melting easily in hot weather.

Among the vegetable oils corn, cotton seed, soya bean, peanut, sesame, olive, rape, cocoanut, castor, and palm oils or animal oils such as those of lard and tallow and other o-leins and palmitins with more or less stearins, all of an animal nature, fish and whale oils, codliver oil and the like may be employed'either in the hydrogenated or unhydrogenatedcondition in compounding products under the present composition.

I have noted that when a vegetable oil such as cottonseed oil is hydrogenated directly until of the consistency desired that on cool ing frequentlyit tends to granulate unless chilled or very rapidly cooled. This is objectionable in culinary operations as an initial lard-like body after once heating and. slow cooling in the air, often forms relatively hard granules of stearin-like bodies which look like little balls of coagulated material and separating as they do from the fluid oil under some circumstances give the product the appearance of having curdled Cr decomposed. By super-hydrogenating and pressing to the point required the granu lating stearins or stearin-like bodies are eliminatedto a greater or less extent and lesseasily crystallizing or non-granulating stiffening bodies remain, tending from their amorphous texture to maintain substantially the original consistency-and appearance of the product in repeated culinary use.

In general I prefer to secure a product point of said product of a range of approximately from above 10 to below 40 C. It of course, may 'varywithin still greater limits according-to climate and seasonal variations of atmospheric temperature. Ordinarily a product having a titer of from about 28 C. to 30 C. is well suited as lard substitute or lard compound. It should be remembered that the titer referred to herein is that not rigidly precise thermometric value derived by cooling some of the melted product and taking the point where the falling thermometrie column becomes stationary which is that point where solidification takes place.

The titer is considerably lower than the melting point.

For the manufacture of butter substitutes as distinguished from lardv substitutes a softer product is desired, one in particular ately melts and does not leave a disagreeable greasy sensation on the tongue and walls of the mouth. In the manufacture of hydrogenated butter substitute as I have set forth in U. S. Letters Patent No. 1,038,545 of Sept. 17, 1912, the step of over or superwhich when taken into the mouth immedicatalyzer to,a' titer of 35 C. to 40 C; and

hydrogenation is desirable. In the above mentioned. patentof which the present appllcation is in a measure'a continuation as regards the step of overhydrogenation, I have specified in particular the manufacture of a butter substitute involvingthe incorporation of hydrogenated edible oil and milk material. It is also possible to make a butterlike composition without the use of milk material, but consisting of simply edible hydrogenated oil with perhaps some flavoring material as valerian ester and the like, salt and coloring matter. The mixture of edible hydrogenated vegetable oil with ordinary butter in aproportion of two parts of the oil to one; part of the butter provides very suitable butter-like material at a relav tively low cost. Hydro enated corn oil,'be-

cause of its flavor is this way. While theprocedure of making either an edible butter-like or a lard-like compound of the present invention varies somewhat esirable' for use in depending upon the oils or fats treated and degree of consistency desired, etc for illustrative purposes, an edible mixture is pre-' pared by taking cotton seed oil and corn oil in the proportion of 4 parts of the former to one part of the latter. The almost tasteless character' of cotton seed oil when highly refined and also when hydrogenated is improved by the addition-of corn or peanut oil giving the product a faintly nutty flavor. c The mixture is super-hydrogenated by the action of hydrogen in the presence of a without forced hydrogenation at excessively high temperatures as hereinbefore indicated.

This is cooled andpressed to bring the prodnot to a titer of about 29 ,C. It is "agitated withi5% more or less of fullers earth at a' temperature of 100 C. or so for about 5 minutes in order to remove any objectionable coloring matter. Or the'pressed superhydrogenated cotton seed oil product obtainedin this way may be mixed with about i 15% or 20% of corn oil to secure the titer desired.

, in this art in a sense which is substantially bodies.

I do not limit myself solely to the use of super-hydrogenated oils or similar fatty Furthermore additions in various proportion of the diiferent-kinds of oils above mentioned may bemade as desired to secure mixtures of hydrogenated and ordinary oils. The defects of the ordinary-oilswheniiot added in large quantities may be in a measure compensated by the presence of the hydrogenated ,productand more particu-' larly by a product which has been. superhydrogenated and' pressed.

Wherever the terms'oils and fat have been used herein, they are applied as is common synonymous, I

in the case of oils containlng considerable To recapitulate myinvention relates to a composition containing edible hydrogenated oils or fats and relates in particular to oily or fatty products preferably of a composite nature containing edible hydrogenated oily' or fattymaterial derived preferably by the over or super hydrogenation of unsaturated oily or fatty. material to afford oils or fats of a'butter-like or of a lard-like consistency or other desired consistency, or say of a titer ranging between 24 C. and 34 (1., which product is essentially or substantially free from deleterious or toxic bodies and also free fatty acids, which is preferably substantially free from coloring matter, odor of origin, or any objectionable 'odor, is preferably essentially stable in storage without action on tin containers, or tendency to rancidify or to acquire a resinous flavor, or to coagulate on standing in storage with for-- mation 'of objectionable masses of granulous stearin like bodies; which stands a relatively high temperature in culinary operations without development of objectionable fumes and which" preferably has a substantially amorphous texture and pronounced melting point lag; and my invention further relates to apro'cess of making theproduct aforesaid.
